Multi Curve

lang:en

A MultiCurve is a 1-dimensional GeometryCollection whose elements are Curves.
A MultiCurve defines a set of methods for its subclasses and is included for reasons of extensibility.
A MultiCurve is simple if and only if all of its elements are simple and the only intersections between any two elements occur at Points that are on the boundaries of both elements.
The boundary of a MultiCurve is obtained by applying the mod 2 union rule: A Point is in the boundary of a MultiCurve if it is in the boundaries of an odd number of elements of the MultiCurve.
A MultiCurve is closed if all of its elements are closed. The boundary of a closed MultiCurve is always empty.
A MultiCurve is defined as topologically closed.
